I bought Three Etchings before but I can not use it because the quality is bad, I bought Condo Tec for the first time this time. I will not turn one of the two by hand, another one is too shabby. Although it is dob plated it seems that the female thread part is working after plating .... Because it is troubled if it does not turn around because it rusts it is not good to have a female screw not being plated on the female dog purchased goods? Well it is bad making and it does not turn by hand before rusting .... I'd like it to be properly decided, but what (model) should I buy?
